Title: Vertical magnetic recorder
Inventor: SAWADA TAKESHI
IPC: G11B5/127
Filed: 1981-04-15
Abstract: PURPOSE:To realize high-density multitrack recording and low power consumption by magnetizing a magnetic recording medium in one direction with a  damagnetizing pole, and flowing a small current through a coil wound around a main magnetic pole. CONSTITUTION:A vertical recording layer 5 is magnetized at a part succeeding a part B opposed to a demagnetizing electrode 11. Then, an auxiliary magnetic pole coil 3 is supplied with an only enough current to invert the magnetism of the vertical recording layer 5 near a part A in the opposite direction to the demagnetizing pole 11. While the current is flowed, magnetic saturation is caused near the tip of a main magnetic pole 1, so lines of magnetic force generated by the auxiliary magnetic electrode 2 never converge there, so that the magnetism is not inverted. Namely, a demagnetization state is still set. In recording by this system, magnetic saturation is caused near the tip (a) of the main magnetic pole 1, so the necessary coil current is very small.

IPC: G06F3/0354
Filed: 1989-03-08
Abstract: PURPOSE:To attain the quick and effective input of coordinates by securing a constitution where a switch is turned on when a mobile control cover plate reaches the termination of its movement and a scrolling action is automatically performed. CONSTITUTION:The switches 20 are fixed at each part of casings 10 set opposite to the fringe part of a mobile control cover plate 12 at each 90 deg. interval against the center of the plate 12. Then the plate 12 moves with an input operation of coordinates. When the plate 12 reaches the termination of its moving range in the due direction, the fringe part of the plate 12 pushes a contact 20C of the switch 20 as shown by a dotted line in the figure. Thus a switching action is performed. When the switch 20 is used as a scrolling switch, for example, the pictures shown on a display are automatically switched. Thus the quick and effective input of coordinates can be attained.
